Ditto on the listen to your body comments.
Today I felled a very large dead fir tree for this winters firewood and so it could be dropped in a controlled way and not come down in a winter storm and damage several high value Pacific Maples nearby.
I had planned to bike today but after felling, bucking to length, loading and unloading 3 chords of firewood my body told me to drive to work today. As I sit here at the end of the day eating stuffed mushrooms and enjoying a glass of cab my body is also saying thank you.
Tomorrow I ride and will feel great. If I had ridden today I would probably feel like crap right now.
